Hi everyone,
I need a current source for my project. I must controlled average output currnet value and dirrection of the current. The average output current value range is 0-5A. input voltage 10V or 5V, switching frequency 50kHz or higher value.
I think that, I can use the full bridge inverter. By this way I can control the direction of the current easly also by changing duty cycle I can control the output value of the average current.
I can read the output current with microcontroller and I can use the PI controller to arange the duty cycle.
in here I have some question;
I do not know load value, it can be very small, so Can I control the average output current with PWM signal?
do you think this is appropriate?
Do you have any other suggestions?
